Thanks for the kind words people. I (Pravin) am on this forum as well but socially, so I do tend to stay away from any sort of "punting" as I hate spammers as much as the next guy.
As mentioned above the 303 AeroSpace protectant is superb stuff. The problem with the cheaper local stuff is most of the interior dressings contain a cheaper grade of silicone which has a detrimental long term effect on plastic surfaces. Not a fan of the Shield retail line but their Professional line has some nice products which we actually have listed on our site.
Another favourite of mine is the
Collinite #855 which can be used on leather and vinyl. It leaves a super matt finish which looks OEM.
If you have further questions, I would be happy to assist.
